To all whom it may concern:

Be it known that I, WALTER'L. HENDRICKS,

a citizen of the United States, and resident of Aurora, county of Kane, and State of 1111'- nois, have invented certain new and useful Improvements n. Harvesting Machines, of

which thefollowing-is a specification, and

whichare illustrated in the accompanying drawings, formingm part thereof H The invention relates'to harvesting -machines, and more particularly to thosehavgrain and tying it driving the operative parts of the machine is usually derived from a single traction wheel known as the bullCwheeLf In order that this wheel may serve .to transmit therequired amount of power,.it is located centrally beneath the operative parts for re-.

ceiving the greater part of the weight of the entire machine. This substantial balancing of the machine upon a singletraction wheel. has numerous disadvantagea among which are the lashing of thedraft-ipo'le from. side to side and a lateral shifting movement of the machine upon encountering obstructions in theground over which it is drawn. .The location of the single traction Wheel directly beneath the operative parts of the machine also makes it necessary to support these parts in an elevated position, with: the result that the grain must be carried'upto them for being tied'into bundles andthe bundles then lowered for being discharged upon the ground. v

The present invention hasfor its ob]ectto provide a harvesting vmachlne of the type described, which shall be of such improved construction as topermit of its being drawn smoothly along the ground-While stillsupplying suflicient tractivepower for driving its operative parts, and to permit all .of the operative parts of themachlne to be located .near the ground.

The invention, accordingly contemplates an improved-form of harvest ng machlne in which the. traction wheels and operative In the accompanying drawings, Figure 1' isa side elevation of a form of harvesting machine embodying the features of improvement proyidedby the invention, some of the parts b eing and others being shown in section; Fig. 2' is a planview of the harvesting machine illustrated'inFig. 1, a different position of certain of the parts being indicated by dotted lines; Fig. 3 is a detail .plan view of the machine showing the parts Specilication of IiettersgPatent.

is a detail sectional view taken on the line the machine are principally associated about a horizontal open frame comprising the front and rear transverse rails I6, 47, and the longitudinal side and intermediate rails 29, 30, 36 and 48. The longitudinal rail 29 is located beyondthe outer end of the apron Q26. This sideof the frame is supported by parts are located upon different transversev lines.

the usual grain wheel 28. At its inner end This roll is journaled at its opposite ends in the front and rear transverse rails 46 and 47. The construction provides for changing the elevation of the sickle bar 25, both by raising and lowering the frame and by adjusting the pitch or inclination of the frame.

For raising and'lowering the frame at one side a well known form ofvertical adjustment isprovided for the grain wheel 28. This mechanism is illustrated in Fig. 9. It

' comprises a bracket arm 31-, having one end pivotally secured to the side rail 29 adjacent the forward edge of the.frame, and

having the grain wheel 28 journaled upon its otherend. 1 p

An ad ustable truss serves for swlnging the bracket 31 to raise and lower the grain 'wheel. This truss comprisesthe usualstrut 32, link 33 and chain 34. A pair of longitudinally .disposed rigid frame members 35 and 36 extend over the first-mentioned frame. These frame members have downwardly curved rear end portions,as 37, 38,

which connect with the rear transverse rail 47. The frame members 35 and 36 are each firmly connected at their forward ends withthe front transverse rail 46, as by uprights 27.- Cross ties 39 serve for connecting the.

two frame members 35, .36, at suitable, in-

. tervals. 'An upwardly inclined stub tongue' 40 is pivotally attached to the-front transverse rail 46, as at 41, and extends forwardly therefrom. A power truck, asthe one generally designated 42, serves for supporting the stub tongue 40. Arear carrying wheel, as 43, is also provided. z

The mechanism for tyingthe, grain int I bundle'smay take any convenient form; of

construction, and will preferably include an inclined table 44, through which the-needle,

as 45, and packers 201 operate in the usual manner. Asshown, the table 44 extends laterally upward from the inner end of the I apron 26, and projects beyond theframe for the delivery of the bundles of grain at that side of the machine which is'rem'ote from the apron. 'A series ofpicker fingers 200, 1

located over the lower edge of the table 44 and operated by a shaft 68, serve for mov- .ing the grain upwardly along the table 44 countershaft is shown at 50, and the shaft I for engagement by the packers 201'. v

A main drive shaft is shown at '49. A

for operating the packers 201 appears at 51. The main' drive shaft is preferably transversely arranged in the machine adjacent transverse rails 46, ,47. The countershaft 50 is operatively'connected to the drive shaft 49 at all times, as by means of the beveled gears shown at 52, 53. 1

The 'countershaft 50 preferably has a sprocket wheel 54-fixed upon its rear end,

and a crank disk 55 fixed upon its forward end. -A pitman 56 operatively connects the crank disk 55 with the sickle bar 25. The sprocket wheel 54 serves for transmitting power to all of the other operative parts of the machine. As shown, a sprocket chain 58 turns over the sprocket wheel 54 and'over sprocket wheels 59 and 60 mounted upon the rear-ends of the packet shaft 51 and roll 57, respectively. 'All of the operative parts of ;the bundle-tying mechanism may receive power through the packer shaft 51 in any well known manner.

As shown, the knotter shaft, shown at 61,

is operatively connected with the packer shaft 51 by an upright shaft 62, and the needle'shaft, as 63, is operatively connected with theknotter shaft 61 by a link 64. A

beveled gear 65,- mounted upon the forward end of the roll 57, serves for transmitting power to the reel, as 66, through an intermediate mechanism (not shown). 'A spur gear 67 is also mounted on the forward end of the roll 57. A second intermediate mecha nismfnot shown) serves for transmitting power from this spur gear to the picker shaft 68.

The front truck, as the one generally designated 42, is preferably so constructed as to serve both for transmitting power to the drive shaft 49 and for guiding, the machine.

This form of front truck is illustrated in detail in Fig. 6. As there shown it comprises a pair of traction wheels 69, 70, and an upright bolster frame 71. The stub tongue 40 conveniently extends through and issuspended fromv the bolster frame 71. As shown, the stub tongue and bolster are connected by staples 72 and 73, which are hooked together and one of which is secured in the stub tongue 40 and the other of which is secured in the bolster frame 71.

When; the operative parts of the machine are to receive power from the movement of the traction wheels, as 69 and 70, over the ground, these wheels are preferably fixed upon the ends of the axle, as 74, for rotation therewith in one direction. Topermit the swinging of the traction wheels 69 and 70 for guiding the machine, the axle 7 4v is preferably made sectional and comprises an intermediate section 175 which "extends centrally through and is journaled in the boi-- ster frame 71, and outer sections 76 and. 77

each connected to the corresponding end of the 'intermediate section 75 by a universal joint, as 78, 79. The-outer sections 76, 77,

of the axle each extend from the adjacent end of the intermediate section 7 5 to the. corresponding one of the traction, wheels 69 and 70.

A swinging bracket, as 80 and 81, is hingedly connectedto the bolster frame 71 at each end for supporting the corresponding outer section 7 3, 77, of the axle 74. To prevent binding of the parts when these outer sections 76 and 7 of the axle are preferably-slidingly journaled, in these brackets.

' the machine a pole, as 95, is'prefe'rably 'pro- A driving sprocket 82 is fixed upon the-intermediate section 75 of the axle 74. 'This sprocket wheel is operatively connec'ted'with the driving'shaft 49 by a sprocket'jchain 83.-

Preferably the sprocket chain ssgturn over a sprocket wheel 84, which is. normally cent faces of the clutch 85 "and sprocket wheel 84 have complementary formed clutch .teeth 86,187. A spring 88 serves formoving the clutch 85 into engagement with the sprocket wheel 84.' This-spring is coiled aboutthe drive shaft 49 and reacts between the clutch 85 and'a shoulder, as 89,v formed upon the shaft.

Anyconvenient means "may be employed "for moving the clutch v85 out of engagement with the sprocket wheel84 against the effort. of the spring 88. Asjshown, a bell crank 90 is pivotally secured upon an adjacent part of the frame of the machine, as the transverse rail' 47, and' has one arm bearing against an annular shoulder 91 formed on the clutch 85. The other arm .of' the j-bell crank-90 is provided with a socket 92 for receiving the,crank .93 of an upright crank shaft 94. The crank shaft 94 is shown as 90 to a conveniently accessible position. 'When a team is to be used for drawing vided. The inner end of this pole isshown' I frame of themachine. The lower end of the" as as being pivotally secured to the stub tongue 40. To this end a bracket '96 is secured against the stub tongue 40 justflin front of its point of connection with the bolster frame 71, and a king bolt 97 extends vertically through the bracket 96 and through the pole 95. In order that the pole 95 may serve for swinging the traction. wheels..69. and 70, a

bracket arm 98, 99, is desirably formed in-.

tegral with each of the bracketsv80 and 81, and extends forwardly therefrom. A link 100 extends between and connects the outer ends ofthebracket arms 98 and 99. This link extends beneath and is pivotally connected to the pole, as by a' bolt 101. A draft appliance, as the evener 102, is'preferably provided. This evener is desirably applied to the forward end of the stub tongue 40..

As shown, a 'clevis 103 ismounted upon the forward end of the stub tongue for connection with the'evener.

.For adjusting the-pitch or the platform 26 a threaded strut 104 extends obliquely between the stub tongue 40 and the threaded strut 104 is shown asbeing proand 116 intermediate their ends.

inclination of' vided with a projecting stud or gudgeon 105.- This gudgeon-normallyenters'a sock- ,eted plate 106, carried by-the stub tongue. vAs shown the socketed' plate 106 ispivotally attached to the. stub tongue 40 to swing in a vertical plane. A nut 107, having threadedengagement with the strutl04, serves for connecting the strut with the frame. This hunt is desirably pivotally secured to the forloosely, mounted on the driveshaft-49 and is arrangedto be rotatably connected-there .with'rby 'a clutch 85. As-shovvn, the adjaward end of the frame member 36*.

Any convenient means may be'employed for rotating the strut 104 to change the the strut'104 byia' knuckle joint, as 111, and extends rearwardly therefrom. A hand 1 wheel 110 is mounted on the rear end of the shaft, and a drivers seat 109 is conveniently located adjacent this hand wheel. As shown, the-drlvers seat rises from and is supported by the frame member .35.

If desired a post 112, which rises from the mainframe member 36* adjacent the vdrivers seat 109, may be provided for supporting the rear end of the shaft 108. As shown, the shaft 108 is slidingly journaled in a collar 113 carried bythe post 112. To permit the necessary tilting of the shaft 108 incident to "the longitudinal movement of the threaded strut 104, the collar 113 is pivotally mounted in the higher end of the post 112.

' The rear carrying wheel 43 may be attaohedto the frame in any convenient manner, but provision will preferably be made for raising and lowering this wheel, for per mitting the wheel to swing when a short turn is to be made with the machine in one direction, and for turning the wheel to a different position when the machine is to be transported from place to place. As shown, a

bracket; generally designated 114, is secured rightpost 117 extending between and con-.

necting the horizontal frame members 115 If desired a toothed quadrant 118 may be formed upon the post 117 at one side of-the bracket. A verticalspindle119 extends through and is slidingly journaled in the horizontal frame "members. 115, 116, of the bracket 114 adjacent their rear ends. A stub axle 120 is secured to the spindle 119 adjacent its end, and receives the wheel 43. .1 1

Theelevation at which the rear end of lo r the main frame is supported by the carry-1.

ing wheel 43 is adjusted-by sliding the spindle 119 up 'or down. For this purpose a hand -leverl2l is conveniently provided. As

plays over the toothed margin of the quadrant, A link 124 extends between the hand lever 121 and the'higher end of the spindle 119. In order that the spindle 119 may roatate when in any position of vertical adjustment, the higher end of the link 124 is secured to a collar 125 which rotatably re- This collar is fixed ceives the spindle. against longitudinal movement on the spindle 119 by being located between a collar 126, which is fixed upon the end of the shaft, as by a set screw 127, and the hub 128 of a crank arm 129 which is also fixed to the shaft. As-the hub 128 of the crank arm 129 serves for receiving the weight of the rear end portion of the machine and transferring it to the spindle 119, it is desirably secured to the spindle by means of a pin 130.

- During the forward movement of the ma chine and during the turning of the same to the right, the rear carrying wheel 43 is preferably held in alinement with the frame. On the other hand, provision is preferably made for permitting the rear carrying wheel 43 to swing to an angular position when the machine is turned toward the left in order that a short turn may be made toward the grain side of the machine. As shown, a link 131 is cb'hnected to the outer end of the crank arm 129 and extends forwardly therefrom. A-yoke 132 is formed.

upon the forward end of the link 131. This yoke serves for pivotally connecting the link to a stud 133. This stud is in turn slidingly connected with a horizontally swinging crank arm 136; For this purpose the stud is provided with a gib 134,- which runs in a slideway 135 formed in the crank arm.

. The crank arm 136 is connected by a pivot bolt 137 to a fixed part of the frame, as by an ex.- tension 138 of one of the cross ties 39. -Most desirably the crank arm 136 is formed with an overturned end portion, as 141, and the pivot bolt .137 passes vertically through this part of the crank arm. In the normal position of the parts the stud 133 is in vertical alinement with the pivot bolt 137, and

' the swinging of the crank arm 136 has no effect upon the angular position of the crank arm 129 or carrying wheel 43.

For swinging the crank arm 136, a link 142 extends between this crank arm and a crank arm 143 mounted upon one of the swinging brackets, as 81, of the front truck 42. When the wheels, as 69,70, of the front truck 42 are turned to the r "lit, the link 142 is drawn forward. This 'moves the crank arm 136 to a position in which that end of the slideway 135 whiclris remote from the line of the pivot bolt 137 is obliquely in front of that end of the slideway which is ward extension of the same.

normally occupied by the gib '134. Movement of the gib in the slideway is thereby prevented and the arm 129 is locked against rearward movement. The rear. carrying wheel 43 is thus held in alinement with the frame. When the wheels, as 69, 70, of the front truck- 42 are swung to the left, the crank arm 136 is moved-to a position in which that end of the slideway 135 which is remote from the line of the pivot bolt .137 is in rear of the pivot. In this position .of the parts the engagement of the rear carrying wheel 43 with the groundwill serve to swing this wheel outward, as the machine is advanced toward the left, the gib 134 sliding obliquely backward in the slideway 135 and permitting the swinging of the crank arm 129 to a position in which the carrying wheel 43 occupies an oblique position. The rear end of the machine will thus be guided toward the right, as the front truck 42 is drawntoward the left, and a short turn of the machine toward the left may be made. .lVhen the wheels 69, 7 0, of the front truck 42 are returned to positions in alinement with the frame, the link 142 will be drawn forward to an intermediate position. This returns the rear carrying wheel 43 to a positionin alinement with the frame. raising and lowering of the spindle 119 will have a slight effect in varying the'distance between the outer end of the crank arm 129 and stud 133, the link-131 is desirably provided with a turn buckle 144 for adjusting its length to. maintain the crank arm 129 and rear carrying wheel 43 in correct posi tion for forward movement of the machine in a straight line at that position of vertical adjustment of the spindle 119 which will be most commonly used. 1

Provision is preferably made for drawing the machine in the direction of the length of the sickle bar 25, when the-machine is to be'transported from place to place. One way in which this may beaccomplished is by transferring the front truck 42 to a position beyond the end of the apron 26, and by swinging the rear carrying wheel 43to the position indicated by dotted lines in Fig. 2. When this is to be donethe carrying wheel 28 is desirably raised to an inoperative position, and a supplemental carrying wheel 145 is applied to the machine in a symmetrical position with reference to the front truck 42 and rear carrying wheel 43.

' The location of the front truck'42 beyond the end of the apron 26 is shown in Fig. 11. For transferring the front truck to this position, the stub tongue 40 is detached from theframe at 41, and a brace rod 146 is secured to the stub tongue to form a rear- The stub tongue 40 is then passed beneath the outer end ofthe apron 26, and the rear. end of the brace rod 146 is inserted in a. socket 147 As the fin-7,104.

provided in one of the intermediate rails, as

30, Qfthe frame. A latch 149, mounted'on the stub tongue 1.0.adjacent its rear end,

serves for connecting the stub tongue with V the adjacent siderail, as 29, of the frame.

,As shown, the latch 149 includes a springbolt 151, and an aperture 152 is formed in n the side rail 29 for receiving the bolt.

l a one quarter turn to the left, as'viewedin V For turning the rear carryingwheel 13 to the position indicated by dotted lines in Fig. 2, the link131 is disconnected fromthe crank arm 129 and the spindle 119 is given Fig. 4. Any convenient means may be employed for securing the spindle 119 against turning when in this position. As shown,- a collar 153 is slidingly.mounted upon the spindle 119 but is fixed, against rotation thereon. The rim of this collar is provided.

' (Fig-5.) for receiving a" latch 155., As shown, thelatch1=155is p'ivot'ally mo'unted uponthe {upper horizontal; frame member 115 of the bracket 114.

with a notch 1.54

When the parts of the machine are in opera'tive :posit ion, this latch is-desirably turned A to theinactive position illustrated in'Fig. 4.

Thecollar 153 is fixed fagainst rotation on the spindle 119 byiforn iing' a key-way 156 in the spindle andibypronidingthe collar;

153 with a set screw 157 dr 'fentering said key-way.'- If desired collar-153 may be held'against vertical movement, as'by means of an overhanging lug .158] formed uponthe upper horizontal framemember 115-1101 collar.

thefr'ea'r carrying wheel 43, as by mounting For securing the-"supplementalcarrying theframe of the machine, a stub axle 159 may be permanently s e'cured wheel 1 145 to to a part ofv the frame at that end remote from upon the front transverse rail 46. -Wheii machine is to betransported from pla'det place, the supplemental carrying fwheel l4'5is temporarily mounted uponfthislstub axle. Usuallythe front-truck 12 will--inelude brace rods, as 160, 161, extending be. tween the bolster frame 71 and stubftongue' 40 for maintaining the bolster framean upright position. Similarly when the frontv truck 42 is located in the position indicated "by full lines in Fig. 2, a brace rod 162 preferably {extends obliquely between the stub tongue40 and apart of the frame, as the front transverse rail 46'.

When the front truck42 is to'be transferred to theposition.

illustrated in Fig, 11,the brace rod 162 may .be removed. jyIt will be observed that if the supple 6 mental carrying ',wheel 1 15 is applied to the 6B the supplemental stub axle 159 before the stub tongue 40 has been detached, that partof the-weight of the machine I which is normally supported by the front truck.42 may be transferred, to

168, mountedupon the opposite ends .of the axle 165 for rotation therewith in-onedirecti'o-n. This form of truck also includes a rigid bolster 169,. IIhe axle 1651s journaled in this bolster, as at 170 and 171., In'this instance an uprightshaft 172 serves as a king bolt for pivotally connecting the stub tongue 1'66 and bolster 169. 'yThis shaft preferably extends centrallythrough the gears,'as 173" and 171, mounted .upon'its opposite ends. The. beveled gear 173 operatively engages a beveled gear 17!? fixed 'upon the axle 165. The beveled 'gear'm operatively engages a 'beveled gear 176.

This last-mentioned beveled-gear is desir= ably mounted'upon oneend of a. short shaft jnaled in a bracket arm; 178 carried by the stub; tongue 166. A sprocket wheel 179, mounted ion the shaft 177, serves to receive he drive'chai'n 83 in lieu of the-sprocket -.Wheel shown at 82in Fig. 6'. 1 v,

A form of construction adapted to supply power in this way is shownin Fig. 10. Inthis instance the rear carrying wheel is indicated at 189. For simplicity of illustration this carrying wheel is shown ,as being secured to the frame by means of the bracket 114, in lieu of the rear carrying wheel. 43, but without means for swinging the wheel for steering. A sprocket wheel 190 is rigidly mounted with the rear carrying wheel 1'89, and a sprocket chain 191 turns over the-sprocket wheel 190 and over a' second sprocket wheel 192 located upon the drive shaft 49.

In-event it should be desired to supply power for driving the operative parts of the machine, both from the front truck, as 42 or 164, and the rear carrying wheel, as 189,

the sprocket wheel 84 and' the sprocket wheel 192 are both mounted upon a sleeve 194 which incloses the drive shaft 49 and is operatively connected to the shaft by a clutch 193. As*shown,'thesleeve 194 is supplied with a series'of ratchet teeth 195, and each of the sprocket wheels 84 and 192 is supplied with a pawl, as 196, for engagement with one of the said ratchet teeth-for turping the sleeve in one direction. mounting the sprocket wheels 84 and 192 permits either to be turned in advance of the other, as upon variations in the relative rate of turning of the wheels of the front truck, as 42 or 164, and the rear carrying wheel 189.-

It will be-noted that the location of the front truck 42 or 1.64 beneath the stub tongue 40, intermediate its ends, and the application of a pulling force to the stub tongue at its forward end, causes this part to act as a lever of which the front truck is the fulcrum. By this means the downward force exerted upon the truck is proportioned to the amount of tractiveefi'ort applied upon the end of the tongue. It therefore follows that the downward pressure exerted upon the traction wheels is proportioned to the resistance'to the forward movement of the machine afforded by the operative parts of the machine. If increased power is required to drive the machine the traction wheels will be pressed against the ground and will 3 This method of chine is running light and no great amount of power will be required for drawing these wheels along the ground.
